My vacuum pump was running every 20-30 sec and I thought it was time to change duckbill valves.
However, it was enough to clean and lubricate the flush ball and ball seal.
I used red rubber grease to lubricate the ball seal and now it works perfectly.

Glad I did not have to do the dirty work to change duckbill valves :)

Easy fixes are always the best! Glad you did not have to dig in to the duckbills.

Vegetable Oil does the job too. I think that’s what they make the red rubber grease out of.
